Specificat'ion of Letters Patent No.`

To all 'whom it may concem Be it known that I, DANIEL TIsDALn, 'of Canton, in the'county of Norfolk and State 'of Massachusetts, pattern-jmaker, have invented a new and usefulV Improvement in` the Mode of Constructing Cooking-Stoves,` called Tisdals Improved Cookng- Stoves, of which the following is a full and exact i the oven and the bottom plate of the stove description.

Figure 1 is a perspective view. Fig. 2`

is a horizontal 'section through line p p.

Fig. 3`is a Vertical section through line g g.:

I first describe my stove as improved by me, and after completing the description shall proceed to specify my improvementsf every part of the stove except myimprovefi ments so specified being in common use.

The bottom plate of my improved stove projects in front as stoves usually do as appears by the letters a a a; a a a Fig. 1 of the annexed drawings, to which I refer as a part of this my specification. Below this projection is a sunken hearth or cavity in which a grate EE on legs is placed4 on which to build a fire with charcoal so as to heat irons or by the use ofa grdiron placed over said grate to broil meat. Said grate may be made in two parts and divided by a partition so as to use one or both a's occasion may require. That part of the hearth which covers the grate slides on and ofl" at pleasure as the drawing Fig. 1 shows. The charcoal is ignted and kept on fire by a draft of air passing through holes in the front part of the bottom of the sunk hearth after having put burning coals there, and the smoke and vapor passes off through holes in that part of the bottom of the hearth plate which projects over the sunken cavity into the fiue which is under the whole of the large oven. The sunken hearth may be made narrow for` one grate only instead of being divided into two as above suggested.

Figs. 1 and 3l letter A is the large oven which is about eight inches from the top to the bottom which occupies the whole of the stove below the fire room, except the small space under the oven throughout occupied by the flue and the small space at each end occupied by a flue. Above the large oven are two small ovens BB Figs. 1 and 3 and between them is the fire room C, all three passing from the front to the back of the stove, as the large oven below, there being no flues in front or in the backside ofthe 1,006, dateanovmber 12, 1838.

stove. The ovensBB do not extend tofthe top of the stove but as will be illustrated by reference to Fig. 3 of the annexed drawin'gs, which is a backside view of the stove, with the back plate taken off, arise no 'higher than'w w, m a: which are the tops of the said ovens. the flue 'b b between the bottom plateof and the'flues,` b Z), b b between theends of the stove and the ends of the ovens.

In Fig. 2 which is a top view' of the stove with'the topvplateltaken off b 7), b b, b b, bi) represent' the endflues which pass down Fig. 3 also represents 1 1 1 1 are the handles of thedampers i 6-6, 6 6, 6 6, 6 6 by which the end flues or either of them may be closed at pleasure.,

There is a small hole communicating with` one of the end flues in each ofthe small ovens to let oif steam arising from articles baked therein. In the fire room is placed the grate D Fig. 1 of which DFig. 3 is a backside view and D Fig. 2 is al side 3 view. On this grate the charcoal is placed or wood.` A draft of air to ignite and' and throwing the flame up so that it may s act more strongly on the boiler as it passes over the tops m w, w a: of the small ovens on toward the flues b, b.

Figs. 2 and 3 5 5, 5 5` is a view of the wind walls from the top end 7 7, 7 7 are views of the partition of which 5 5, 5 5 are a continuation. From the flues b, b Fig. 3, end views of b b, b b, b b, b b`F-ig. 2,

lthe smoke and fiame passes down into the fiue b b, following the course of the red dotted lines, between the bottom of the stove and the bottom of the large oven and thence out at F, the receiver of the pipe represented by dotted lines. i

Figs. 1 and 2 3, 3; 3, 3 3 3 are the boiler4 holes and Fig. 3 3, 3 3 represent the spaces filled by the three back boilers when 'inserted.

Fig. 2 8 8, 8 8 are views from top of plieces of loose iron fitted in to increase the distance and thickness between the fire room and the side ovens so as to prevent the heat from acting too violently on the ovens and Fig. 3

8 8, 8 8 are back and end views of the same pieces.

The stove contalns six boilers, on two of which over the fire room the heatacts directly, and on the four other boilers over and B B are back views of 'the small side ovens. H Figs. 1 and 3 door over which access is had to the flueunder the oven for cleaning it.l There are apertures in the rear side of the fire `Chamber similar to thoseV in front marked 2 for increasing the draft.

VVhat I claim as my inventon and desire to secure by Le'tters Patent is The general construction and arrangep ment 'of the stove as above set forth, that is vto say, a stove having a large oven cover; ing the whole of the bottom plate, with the exception of the flue spaces, in combination 'with the fire chamber and two side ovensV placed above it; Vand 'with the respective flues and their appendages conducting the draft in the manner above described, or with such variations only, as will leave the'structure substantially the same.
